Yes. The images (text, graphics) are processed and transferred onto a heated roller that then transfers the image onto paper. Dry toner powder and heat are used in laser printing (as opposed to liquid ink in an inkjet printer).
Laser printers use a drum and toner.

Spooling is basically a means of saving information that cannot be handled immediately. For instance, when printing a document, the document has to undergo a conversion process. This can often be a lengthy process when printing directly to the printer, thus a print spooler handles the actual conversion and queues your document ready for printing when the printer is ready. This allows you to continue working while the spooler works in the background.
Yes, printers have memory built-in, used to store printing data while the printing is in process. Some printer types must compose the entire page in memory prior to the actual printing, others use the memory to buffer some print. All printers will have such memory, but inexpensive models might be designed with the bare minimum of memory (in order to save cost on the printer).
Laser printers use a drum and toner in the printing process.
First, postcard printers must choose good quality paper of the proper thickness; if it's too thin the postcard will get damaged in the mail. Modern postcards are usually printed using the offset printing process, in which the inked image is transferred first to a metal plate and then onto a rubber blanket and finally onto the printing surface.
The printing of menus should be addressed in the beginning of the event planning process. This will create plenty of time to make necessary changes or corrections to the document.
You can find information on different types of catalogue printing equipment by visiting websites of printing equipment manufacturers, reading industry publications that focus on printing technology, attending trade shows or conferences related to printing, and contacting printing equipment suppliers for product catalogs and information.
Printing takes time because the printer needs to receive the document data, process it, transfer it to the printing device, format it according to the desired settings, and then physically apply the ink onto the paper. Each of these steps requires time to complete, resulting in the overall printing process taking time to finish.
